UV/H2O2, O-3 and (photo-) Fenton as treatment prior to granular activated carbon filtration of biologically stabilized landfill leachate

摘要

BACKGROUNDLandfill leachate requires rigorous treatment to limit environmental impact. Often, granular activated carbon (GAC) filtration is part of the treatment train. Little is known on how a preceding (advanced) oxidation process (AOP) could modify the adsorption properties. As such, different AOPs were compared as preceding step to GAC filtration for treatment of biologically stabilized landfill leachate.
